Array measurements ROBAT 226.238:

• 5 mic array adafruit 5 i2s
• 96khz
• 2 meters distance (~ far field = 10𝛌; 𝛌max = fmin; 343/2 = 171 Hz --> 10𝛌 = 1715 Hz; at 1000Hz: 6𝛌 = 6*0.343 = 2.04 m)
• measured clockwise (R: 0-90; L: 270-360)
• array rotated around the central mic kept a 2m from source

HW settings:

• AWR 445 vol = -40 db
• fireface analog out 1/2 stereo vol = 0db
• tweeter #1

NOTE: some sweeps sometimes sounded cropped or incomplete. Measures of 0 deg, 100 to 260 deg have been taken with the same setup but on 2/4/2025

Output signal

Out signal used during the recordings: 1-40Khz 5ms sweep.

Final notes

• 3 mics have a negative bias around -0.053, mic 3 at -0.065 and mic 4 at -0.060.
• There is a different zero bias across microphones, but the diffence is pretty low (approximately 10% of the first sweep amplitude)
• frequency analysis shows a clear pattern connected to the microphopne position along the array: mic1 (on the left of the robot) has a bias to pick up more on its left side across all frequncies. Similarly for mic5 (last on the right) accordingly.
